therefore Cos(A+A)= CosACosA - SinASinA
= Cos^2A - Sin^2A</span>

Required
Is the pie chart appropriate
The attached pie chart displays the distribution of each of the 4 genre. The partition occupied represents the measure of each genre.
Answer: a) There are 42% chances that both units will meet their objectives.
b) There are 88% chances that one or the other but not both of the units will be successful.
Step-by-step explanation:
Since we have given that
Probability that the Red unit will successfully meet its objectives = 60% = P(R)
Probability that Blue unit will successfully meet its objectives = 70% = P(B)
Probability that only Red unit will be successful = P(only Red) = 18%
As we know that

Hence, there are 42% chances that both units will meet their objectives.
the probability that one or the other but not both of the units will be successful is given by

Hence, there are 88% chances that one or the other but not both of the units will be successful.
