A bag contains 31 red blocks, 47 green blocks, 23 yellow blocks, and 24 purple blocks. You pick one block from the bag at random. Find the indicated theoretical probability. P(yellowyellow or purplepurple)

0.07072

Step-by-step explanation:

Red Blocks= 31

Green Blocks= 47

Yellow blocks = 23

Purple blocks= 24

Total= 31+47+23+24= 125

P(Yellow) = 23/125

P(Purple)=24/125

NOTE: AND (X), OR (+)

P(yellow yellow or purple purple)

= P(Y and Y) + P(P and P)

=(23/125 X 23/125) + (24/125 X 24/125)

=529/15625 + 576/15625

=1105/15625

=221/3125

=0.07072

Therefore:

Probability of Picking Yellow Yellow or Purple Purple is 0.07072.
