Question

11) There are 10 balls in a box numbered 0 to 9. If we select 4 balls randomly then find

the probability that we will never get the ball having number 0​

Answer 1

Answer:

if we select 4 balls randomly out of 10

ball

clearly there should no 0 ball out of that 4 balls

probability of 4 balls will be 4/10 = 2/5

where there should no 0 ball which is one in no. and may selected out of these 4 balls

so ,

1- 2/5 = 3/5

Answer 2

Answer:

Step-by-step explanation:

we have 10 balls

now we must select all balls except for 0

total = 10

favorable choices (1, 2, 3...9) = 9

probability of not selecting 0 in the first chance = 9/10

now total balls = 9 (one has been chosen)

favorable choices (except for 0) = 8

probability of not selecting 0 in the second chance = 8/9

therefore for 4 chances

9/10 x 8/9 x 7/8 x 6/7

6/10 answer
