If a jelly bean machine contains 16 pink jelly beans, 34 blue jelly beans, 24 black jelly beans, and 26 purple jelly beans, what is the probability that a jelly bean chosen at random will be black?

The probability is 0.24.

Step-by-step explanation:

Given,

The numbers of pink jelly beans = 16,

Blue jelly beans = 34,

Black jelly beans = 24,

Purple jelly beans = 26,

⇒ Total jelly beans = 16 + 34 + 24 + 26 = 100,

Hence, the probability that a jelly bean chosen at random will be black

if x decreases by 4 then y increases by 10
