Look at the tree diagram for tossing a coin three times. Find the probability of getting exactly two tails.
A . 3/8
B . 1/4
C . 3/4

3/4

Step-by-step explanation:

use a calculator

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

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
