Question

a basket contains 50mangoes of which 20 are unripe other basket contain 40 of which 15 unripe one mango is taken from each box find the chance that 1 )both are ripe 2)both are unripe 3) atleast on ripe?​

Answer 1

Answer:

We can choose a pair of mangoes in 50×40=2000 ways.

The first basket has 50 - 20 = 30 ripe mangoes.

The second basket has 40 - 15 = 25 ripe mangoes.

Each ripe mango from the first basket paired with a ripe mango from the second gives  30×25=750 pairs.

So, the probability of both being ripe = 7502000=38.
