Three coins are tossed simultaneously 200 times with the following frequencies of different outcomes:

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 occurrences

The 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 = 200

Number of 2 heads outcomes = 72

Probability of 2 heads outcomes = Number of 2 heads outcomes / Total number of tosses

= 72/200

= 9/25
