If 3/5 are action and 1/4 are comedy then:
(3/5)+(1/4) are action or comedy
To add/subtract fractions you need a common denominator...
(3/5)*(4/4)+(1/4)(5/5)
(12/20)+(5/20)
17/20
So 17/20 (85%) of his collection are action or comedy not 4/9...
P(z < 3)
From the normal distribution table,
P(z < 3) = 0.9987
Betina is 155 centimeters tall or 1 meter and 55 centimeters
1 meter = 100 centimeters
100 + 87 = 187 , Brian’s height in centimeters
Since Bonnie is 58 centimeters shorter we will subtract 187-58 which gives us 129 centimeters.
Betina is 26 centimeters taller than Bonnie so we add 26+129 =155
Therefore Betina is 155 centimeters tall or 1 meter and 55 centimeters.
Hope this helped! :)
