A bag contains red yellow and green pegs. A peg is taken out at random from the bag. The probability that it is red is 0.35 the probability that it is green is 0.4. find the peg selected is yellow not red

The probability that the peg selected is yellow is 0.25

Step-by-step explanation:

The bag contains Red, Yellow and Green Pegs.

P (Red) = 0.35

P (Green) = 0.4

P (Yellow) = ?

The sum of any probability is always equal to 1

Therefore:

P (Red) + P (Green) + P (Yellow) = 1

0.35+0.4+P (Yellow) = 1

0.75+P (Yellow) = 1

P (Yellow) = 1-0.75

P (Yellow) = 0.25

The probability that the peg selected is yellow is 0.25
