Question

¿Qué probabilidad se tiene de que la mosca de alas normales tenga los ojos bermellón?

Answer 1

There's a 1% of probability for bermellón flies.

Explanation:

The missing information is

tamaños de alas

color de ojos / normal / miniatura

-normal / 140 / 6

-bermellón / 3 / 151

If we sum all types, we have a total of 300 of total possible outcomes, but only 3 are events related with the probability we are looking for, because there are 3 bermellón flies.

So, the probability would be determined by the ratio

`P=(3)/(300)=0.01`

Which means there's a 1% of probability for bermellón flies.
