If Terri had 5 blouses and 3 pairs of pants, Teri could wear 15 different combinations of clothes. 1 blouse can be worn with any of the three pairs of pants, as for the other 4. 5 * 3 = 15. The answer is 15 combinations.
1*23 equals 23.
23 is a prime number so it doesn't have any factors besides 1 and itself.
Answer:
7/8
Step-by-step explanation:
The numbers that are not 3 are 1, 2, 4, 5, 6, 7, and 8.
7 out of 8 numbers.
P(not 3) = 7/8
Answer:
the conditional probability that X = 1 , X = 2 and X = 3 is 0.7333 (73.33%) , 0.25 (25%) and 0.0167 (1.67%) respectively
Step-by-step explanation:
a player wins money when i>0 then defining event W= gain money , then
P(W) = p(i>0) = p(1)+p(2)+p(3)
then the conditional probability can be calculated through the theorem of Bayes
P(X=1/W)= P(X=1 ∩ W)/P(W)
where
P(X=1 ∩ W)= probability that the payout is 1 and earns money
P(X=1 / W)= probability that the payout is 1 given money was earned
then
P(X=1/W)= P(X=1 ∩ W)/P(W) = P(X=1) / P(W) = p(1) /[p(1)+p(2)+p(3)] = 11/40 /(11/40+3/32+1/160
) = 0.7333 (73.33%)
similarly
P(X=2/W)=p(2) /[p(1)+p(2)+p(3)] = 3/32 /(11/40+3/32+1/160
) = 0.25 (25%)
P(X=3/W)=p(2) /[p(1)+p(2)+p(3)] = 1/160 /(11/40+3/32+1/160
) = 0.0167 (1.67%)
Answer:
perpendicular
Step-by-step explanation:
2-x =3y
3y = 2-x
y = -1/3x+2/3
slope is -1/3
2y +10 = 6x
2y = 6x -10
y = 3 -5
slope is 3
-1/3 and 3 are negative reciprocals so the lines are perpendicular.
