Answer:
39.16% probability of selecting three Democrats and three Republicans
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the order in which the people are selected is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
3 Democrats, from a set of 8.
3 Republicans, from a set of 8.
Total outcomes:
6 people from a set of 16.
Probability:
39.16% probability of selecting three Democrats and three Republicans
Answer:
24% probability that both fund A and fund B will rise in price
Step-by-step explanation:
We have these following probabilities:
40% probability that fund A will rise in price.
If fund B rises in price, 60% probability that fund B does.
What is the probability that both fund A and fund B will rise in price
40% of A, and if A rises, 60% is B. Since the only outcome that interests us is both rising in price, we multiply these probabilities
24% probability that both fund A and fund B will rise in price
Answer:
y = -3x - 2, the slope is -3 and the y-intercept is -2
Step-by-step explanation:
2y +4 = -6x and minus the four to get 2y alone
Then divide -4 and -6x by 2 to get y = -3x and -2
Angles of a pentagon = 108°
angles of a square = 90°
108+90
answer= b
2/5m = 750
m = 750 * 5/2
m = 3750/2
m = 1875 <== monthly income
