on an eight question true false quiz a student guesses each answer what is the probability that he gets at least one of the answers correct?

the probability of getting at least 1 answer correct = 1 - probability of getting all answers correct.so in your case it for be p(at least 1 answer correct) = 1 - 1/256where 256 is your sample space, |s| = 2^8.


the probability that an individual is left handed is 0.1 in a class of 30 students what is the probability of finding at least 5 left hander's?

this is a binomial probability distribution. the number of trials, n, equals 30; and the probability of success is p, which is 0.1. in this problem, you want the probability of at least 5, which is the complement of at most 4. we use the complement because we can subtract from 1 that probability and we will have the solution. the related link has the binomial probability distribution table which is cumulative. per the table, at n=30, p=0.1 and x = 4; the probability is 0.825. therefore the probability of at least 5 is 1 - 0.825 or 0.175.

when tossing 5 coins simultaneously find the probability that at least 1 head is showing.?

this is easiest to solve by working out the probability that no heads show and subtracting this from 1 to give the probability that at least one head shows: assuming unbiased coins which won't land and stay on their edge, the probability of head = probability of tail = ½ → probability no heads = probability 5 tails = ½^5 = 1/32 → probability of at least one head = 1 - 1/32 = 31/32 = 0.96875 = 96.875 % = 96 7/8 %


what is the probability of flipping a head when you roll a coin 3 times?

if it is a fair coin, the probability of getting at least one head from 3 flips is 7/8if it is a fair coin, the probability of getting at least one head from 3 flips is 7/8if it is a fair coin, the probability of getting at least one head from 3 flips is 7/8if it is a fair coin, the probability of getting at least one head from 3 flips is 7/8


if 20 percent of people who enter store buy something and 3 people enter what is the probability of at least one sale?

the probability of at least one event occurring out of several events is equal to one minus the probability of none of the events occurring. this is a binomial probability problem. go to any binomial probability table with p=0.2, n=3 and the probability of 0 is 0.512. therefore, 1-0.512 is 0.488 which is the probability of at least 1 sale.

what is the probability of getting at least one head on three tosses of a coin?

in the experiment of tossing a fair coin 3 times, the sample space is made of thefollowing 8 equiprobable events: s = {hhh, thh, hth, hht, tth, tht, htt, ttt}.the events that at least have one head are 7. so the probability of getting at leastone head on three tosses is: p(at least one h) = 7/8 = 0.875 = 87.5%

if the overall percentage of success in exam is 60 .what is probability that ouit of group of 4 students.at least one has passed?

this is a binomial probability distribution; n=4, p=0.6. the probability of at least 1 passed is equal to the probability of 1-none passed; so x=0. the probability of x=0 (with n=4, p=0.6) is 0.0256. so, the probability of at least 1 passed is 1-0.0256 or 0.9744.

what is meant by the median of a set of data?

in probability theory and statistics, a median is described as the number separating the higher half of a sample from the lower half.so if you have 19 measurements and order them from least to greatest, the tenth value is the median.
