Question

A box contains four red, three blue, and six green lenses. two lenses are randomly selected from the box. find the probability of getting two red lenses when two are selected if the first selection is not replaced before the second selection is made

Answer 1

The probability of getting two red lenses when two are selected will be 2/13.

What is probability?

The probability of favorable events to the total number of occurrences.

A box contains four red, three blue, and six green lenses.

Two lenses are randomly selected from the box.

Then the probability of getting two red lenses when two are selected if the first selection is not replaced before the second selection is made will be

The total number of the event will be

Total event = ¹³C₂

Total event = 78

Then the favorable event will be

Favorable event = ⁴C₁ x ³C₁

Favorable event = 4 x 3 = 12

Then we have

P = 12 / 78

P = 2/13
