Question

A die is rolled 200 times and its outcomes are recorded as below:Find probability of getting:. (i) A prime number (ii) Multiples of 2​

Answer 1

Answer:

(A) The only even prime number Is 2.

Which occurs 35 times.

So it's probability = 35/200

= 7/40.

(B)there are only two multiples of 3 I.e 3&6.

So both of these occur

= 40.+ 30 = 70 times

So, it's probability = 70/200 = 7/20.

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

(A) The  prime numbers are 2, 3, 5

Which occurs 35,40,42 times respestively.

So it's probability = 177/200

(B)there are only three multiples of 2 I.e 2, 4,&6.

So  these occur

= 25+28+ 30 = 83 times

So, it's probability = 83/200
