Question

there were 3 coins and they were tossed 200 times total. 23 times, 3 of them showed heads, 72 times, 2 of them showed heads, 77 times, 1 of them showed heads, 28 times, 0 showed heads. whats probability for each of the events?

Answer 1

Explanation:

If the three coins are simultaneously tossed again, compute the probability of 2 heads coming up.Solution:Probability of an event, P(E) = Number of occurrences where the event takes place / Total number of occurrencesThe probability of 2 heads coming up when three coins are tossed simultaneously is given by the ratio of the number of times a particular outcome occurs to the total number of tosses.Total number of tosses = 200Number of 2 heads outcomes = 72Probability of 2 heads outcomes = Number of 2 heads outcomes / Total number of tosses= 72/200= 9/25
