Question

Looking at the ping-pong ball toss board below, whats the probability of landing on a gray square? (Note the board contains 5 rows of 5 squares.)

Answer 1

the probability of landing on a gray square = 5/25 = 1/5

answer
D. 1/5

Answer 2

Option D.
`(1)/(5)` is the correct option.

Explanation:

Total number of solution sets n(S) (sample space) = 5×5 = 25

(Since a ping-pong ball can land on any block of the toss board so total number of events which can occur will be = 25)

Now preferred events n(E) = 5

(Since number of grey squares where ping-pong ball can land are = 5)

Therefore probability of landing of ping pong ball on a grey square P(E) =
`(n(E))/(n(S))`

P(E) =
`(5)/(25)`

P(E) =
`(1)/(5)`

Therefore, Option D.
`(1)/(5)` will be the answer.
