4.
From the numbers 1, 3, 5, 7, 9, 11, 15 a number is to be picked up at random. What is the
probability of choosing a number?
(a) less than 8 (b) 5 or more​

Answer 1

Answer:

(a) 4/7 (b)5/7

Step-by-step explanation:

(a) Probability=Favourable outcomes/Total No. of outcomes

Therefore, P(less than 8)= 4/7 [i.e 1,3,5 and 7]

(b) Probability=Favourable outcomes/Total No. of outcomes

Therefore, P(5 or more)=5/7 [i.e 5,7,9,11 and 15]
