Paco uses a spinner to select a number from 1 through 5, each
with equal probability. Manu uses a different spinner to select
a number from 1 through 10, each with equal probability.

What is the probability that the product of Manu's number and Paco's number is less than 30? Express your answer as a common fraction.

Answer 1

create a set ..
what are various possibilities for the product to be less than 30..

(1,1) (2,1) (3,1) (4,1) (5,1)
(1,2) (2,2) (3,2) (4,2) (5,2)... and so onn

Answer 2

R u getting it ?? i mean is it understandable?

Answer 3

what i did is, consider Paco`s spin Manu`s and say if they both get one, then the product is 1*1 = 1.. which is less than 30..
similarly, noy paco get 2 and Manu still has 1 in the spinner then the product is 2*1 which is again less then 30...

We have to calculate till the time product reaches to 30 or more.. for instance, paco get 5 and Manu get 6.. then 5*6 = 30.. so it is void and we will not consider that

Answer 4

So what is the probability?
