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 |

If the three coins are simultaneously tossed again, compute the probability of 2 heads coming up.

#### Solution

Number of times 2 heads come up = 72

Total number of times the coins were tossed = 200

`"P(2 heads will come up) "="Number of times 2 heads come up"/"Total number of times the coins were tossed"=72/200=9/25`
