How to solve probability
WebA deck of cards has 26 black and 26 red cards. The probability of choosing a red card randomly is: P ( r e d) = 26 52 = 1 2. The probability of choosing a second red card from the deck is now: P ( r e d) = 25 51. The probability: P ( 2 r e d) = 1 2 ⋅ 25 51 = 25 102. Two events are mutually exclusive when two events cannot happen at the same time. WebTo get the overall probability of offspring with the dominant phenotype for all four genes, we can multiply the probabilities of the four independent events: (3/4) \cdot (1/2) \cdot (1) \cdot (1/2) = 3/16 (3/4)⋅(1/2)⋅(1)⋅(1/2) = 3/16.
