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.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

what is the original number? you forgot to add it.
