Since, both the events are independent.
So, P(A+B) = P(A)×P(B)
a) P( Head & Getting a 2 ) = P( head ) × P( Getting a 2 )
b) P( Even number & Tail ) = P( Even number ) × P( Tail )
Hence, this is the required solution.

Answer:
There is a 45.05% probability that the selected person is a right-handed female.
Step-by-step explanation:
We have these following probabilities
A 50% probability that a person is a male
A 50% probability that a person is a female.
A 12.6% probability that a male is left-handed.
A 9.9% probability that a female is left-handed.
If a person is selected at random, to find the probability that the selected person is a right-handed female, one would compute:
50% are female.
9.9% of the females are left-handed, so 100-9.9 = 90.1% of the females are right handed.
So
There is a 45.05% probability that the selected person is a right-handed female.
