Answer 1

I hope its help u....

Answer 2

P(E) = Number of favourable outcomes / total outcomes

P(divisible by 2 or 5) = 2,4,5,6,8,10,12,14,15,16,18,20,22,24,25,26,28,30,32,34,35,36,38,40,42,44,45,46,48,50

P(divisible by 2 or 5) = 30/50
= 3/5 (Answer)


now....bothe divisible 2 and 5
first of all make the factor of 2 and 5
=10
P(both divisible by 2 and 5) = 10 , 20 , 30 ,40 ,50

P( both divisible by 2 and 5) = 5/50
1/10 (Answer)


Hope its help you
