Question

Mr. Lance keeps a jar of candy on his desk for students to pick from when they do well on a test. The jar contains 5 Snickers, 2 Butterfingers, 4 Almond Joys and 3 Milky Ways. If two students get to pick candy from the jar, what is the probability that the first student picks a Snickers and then the second student also picks a Snickers?

Answer 1

3/14 for the first kid and 2/13 for the 2nd kid

Answer 2

Answer:
`(10)/(91)`

Explanation:

Given : The jar contains 5 Snickers, 2 Butterfingers, 4 Almond Joys and 3 Milky Ways.

Total candies in the jar =
`5+2+4+3=14`

Provability that firsts student select snickers =
`(5)/(14)`

Now total candies in jar = 14-1=13

Total snickers remained =5-1=4

Probability that the second student also select snickers=
`(4)/(13)`

Then, the probability that the first student picks a Snickers and then the second student also picks a Snickers :-

`(5)/(14)*(4)/(13)=(20)/(182)=(10)/(91)`

Hence, the required probability =
`(10)/(91)`
