yellow

Step-by-step explanation:

think ! use common sense ! there is no tricky mathematical formula necessary.

how many cases do we have overall ?

13 red

15 yellow

10 blue

7 green

5 orange

in total : 50

and now what is 3/10 of 50 ?

we simply multiply

50 × 3/10 = 5 × 3 = 15

and what color had 15 appearances in these 50 tries?

yellow.

that is really all to do.

a probability is always the ratio (quotient) of actual vs. possible cases.

in these 50 attempts every color had theoretically the chance to "win" 50 times. these are the possible cases.

and then every color has a certain number of actual appearance. the actual cases.

so, red has the probability 13/50.

yellow 15/50 = 3/10

blue 10/50 = 1/5

green 7/50

orange 5/50 = 1/10
