Answer:
The product rule of probability tells that to determine the chances of independent events, such as the likelihood of inheriting a certain allele, probabilities are multiplied
Step-by-step explanation:
The product rule of probability states that the probability of independent events occurring together can be gotten by multiplying the probability of each event occurring alone.
The product rule is given as P(A*B) = P(A) *P(B). Where A and B are two independent events. For example when picking cards from a deck of 52 cards, the probability of getting an ace is 4/52 = 1/13 (because there are 4 aces in a deck of 52 cards) . The probability of picking a heart is 13/52 = 1/4. Therefore the probability of picking the ace of hearts is 1/4*1/13 =1/52.
Jose's age is 10 years
working
let jose's age be x yrs
4x-3=3x+7
x=10
to prove this point replace x with 10 in the equation above
9514 1404 393
Answer:
4. (4, 5)
Step-by-step explanation:
Use substitution to put the value for y in the second equation.
-3x +4(5) = 8
-3x = -12 . . . . . . . subtract 20
x = 4 . . . . . . . . . . divide by -3
The solution is (x, y) = (4, 5).
