Answer 1

Answer:

A. 1 by3 B. 1 by 4

Step-by-step explanation:

A.

We know,

Probability = number of trails in which the event happened ÷ Total number of trails

So, here

Number of trails in which the event happened =4

Total number of trails =(3+5+4) = 12

Therefore, probability = 4÷12= 1 by 3

B.

We know,

Probability = number of trails in which the event happened ÷ Total number of trails

So, here

Number of trails in which the event happened = 3

Total number of trails = 12

Therefore, probability = 3÷12 = 1 by 4
