Three coins are tossed simultaneously 20...

Three coins are tossed simultaneously 200 times with the following frequencies of different outcomes: Outcome: 3 heads 2 heads 1 head No head Frequency: 23 72 77 28 Find the probability of getting: (i) three heads (ii) two heads and one tail (iii) at least two heads

Text Solution

Verified by Experts

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`
