Three coins are tossed simultaneously 20...

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

A

`16/25`

B

`7/25`

C

`8/25`

D

`9/25`

Text Solution

Verified by Experts

The correct Answer is:
D
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`
