Answer:
P(A and B) = 1/4
Step-by-step explanation:
Since A and B are not linked. The event is said to be independent events:
Therefore;
P(A and B) = P(A) × P(B)
Where; P(A and B) is the probability that both A and B are in the same gamete.
P(A) = 1/2 => Probability of allele A in the gamete
P(B) = 1/2 => Probability of allele B in the gamete
Thus,
P(A and B) = P(A) × P(B) = (1/2) * (1/2) = 1/4 = 0.25.
Answer: 7/12
Step-by-step explanation:
From the question, we are told that Chelsea plays soccer 4/12 of the year and swims 3/12 of the year before taking a break from playing sports.
The fraction of the year that Chelsea spend participating in sports will be the addition of the fraction used for playing soccer and the fraction use for swimming. This will be:
= 4/12 + 3/12
= 7/12
Answer:
