Question

15. What is probability that a number selected from the numbers 1, 2, 3, ....., 10 is a
multiple of 3 ?​

Answer 1

Total No. Of outcomes = 10

No. of outcomes as multiple of 3= 3 ( i.e 3,6,9 )

P ( E ) = No. Of outcomes/ Total Outcomes

P(getting a number which is a multiple of 3) = 3/10

Answer 2

Here is the answer to your question!

_____________________________

Total no.of possible outcomes= 10 ( 1,2,3,4,5,6,7,8,9,10)

____________________________

Multiple of 3 = 3,6,9

So favourable outcomes= 3 (3,6 and 9)

____________________________

To find the possibility:

:- No. Of Favourable outcomes by Total No.of possible outcomes.

= 3/10

_____________________________

Answer is = 3/10
