Question

Cards numberd from 6 to 50 find the probability of getting neither divisible by 5 nor 10

Answer 1

Answer:

13 by 10

Step-by-step explanation:

as we can explain it from 1 to 50-4 then,

probability of getting no. not divisible by 5 = 9/46

probability of getting no. not divisible by 10 = 4/46

now,

probability of getting no. not divisible by 5 nor 10 = 9/46 + 4/46

= 13/46

Answer 2

Answer:

36/45 = 4/5

Step-by-step explanation:

total no. of outcomes: no. of cards

                                     = 45

no. of favorable outcomes: (45- no.of cards divisible by 5 or 10)

                                            = 45-9

                                            = 36

therefore probability = no. of favorable outcomes / total no. of outcomes

                                   = 36/45

                                    = 4/5
