Question

the 7. A carton contains 5 defective shirts and 25 25 defect-free shirts. Find the probability of pulling out a (a) defective shirt (b) defect free shirt.​

Answer 1

Answer:

(a) 5/30 (b) 25/30

Step-by-step explanation:

total shirts= 5+25= 30

P(E)=n(E)/n(S)

Answer 2

Answer:

a] number of possible outcomes=30

number of favourable outcomes=5

probability = number of favourable outcomes/number of possible outcomes

                    =5/30

                     =1/6

b] number of possible outcomes=30

number of favourable outcomes=25

probability = number of favourable outcomes/number of possible outcomes

                   =25/30

                    =5/6
