Question

The probability of getting a 1 is 0.3

Answer 1

Answer: 45

Step-by-step explanation:

To calculate the probability of the number of times a 1 we appear , we have

number of times a 1 appeared / Total number of times the die is rolled.

Let x represent the number of times a 1 is gotten

And we have been given the probability of getting a 1 and also the total number of times the die is being rolled , substituting this inside the formula above , we have

0.3 =  x / 150

x = 150 x 0.3

x = 45
