Answer 1

Answer:

probability of

a) even no:- 12/25

b)prime no.:- 9/25

c) multiple of 6:- 4/25

Answer 2

Given:

We have in box card numbered are1 to 25.

To FInd:

Find the probability of getting

a) even no. ,b)prime c)multiple of 6​

Step-by-step explanation:

• We know probability of event is given by the formula

                     $P(E)=\frac{\textrm{no. of possible outcome}}{\textrm{total no. of term}}$

• a) Even no.-

         In given numbers we have 2,4,6,,,,24total 12 even no.

            $P(even)=\frac{12}{25}$

• b) Prime no.

         In given numbers we have 2,3,5,7,11,13,17,19,23total 9 prime no.

           $P(prime)=\frac{9}{25}$

• c)Multiple of 6

        In given numbers we have 6,12,18,24total 4 multiple of 6.

           $P(Multiple of6)=\frac{4}{25}$
