Question

a die is thrown n number of times and out of which the odd output has occurred 350 times. if the probability of getting an even output is 9/16 then find the value of n​

Answer 1

Number of times the dice was thrown = 800 times.

Step-by-step explanation:

Given: A dice is thrown n number of times and out of which the odd output has occurred 350 times. The probability of getting an even output is 9/16.

Find: value of n.

Solution:  

Number of odd outcomes = 350​

Probability of getting even output = P(E) = 9 / 16

Probability of getting an odd output = 1 - 9/16 = P(O) = 7 / 16

Probability of odd output = number of odd output / total number of outputs

7/16 = 350 / n

Therefore n = 350 * 16/ 7 = 800

Number of times the dice was thrown = 800 times.
