Question

A coin is tossed 15 times and observed that 11 times head came up.Find the probability that a tail comes up

Answer 1

Answer:

The probability that a tail comes up is $\frac{4}{15}$  

Step-by-step explanation:

Given : A coin is tossed 15 times and observed that 11 times head came up.

To Find : The probability that a tail comes up ?

Solution :

A coin is tossed 15 times.

i.e. total number of outcomes = 15

11 times head came up.

Chances to get tail is 15-11=4

Favorable outcome that a tail comes up = 4

The probability that a tail comes up is given by,

$P(X)=\frac{\text{Favorable outcome}}{\text{Total number of outcome}}$

$P(T)=\frac{4}{15}$

Therefore, The probability that a tail comes up is $\frac{4}{15}$

Answer 2

Step-by-step explanation:

here is your answer

Therefore the probability that a tail comes up is 4/15
