Question

bob is picking randomly from a bag containing tiles member 1 to 10. write down the probability that the number he picks is 7

Answer 1

Explanation:

a) No of outcomes= 7

total no of outcomes= 10

probability = no of outcomes/total no of outcomes

=7/10

b) 4/10 ( since the outcomes could be 1,2,3,4)

c) no 1 to 10 has 5 odd numbers

so, probability = 5/10 = 1/2

d) multiples of 3 from 1 to 10 are :-

3,6,9= 3 no's

so probability = 3/10
