Step-by-step explanation:
a)
well, logically, it must be M, 2
b)
this is a combined probability for one single pair of possible outcomes.
there are 15 pairs, all with the same probability.
so, P(Q, 4) = number of desired outcomes / number of possible outcomes = 1/15
as combined probability we can also say the probability to get 4 on one wheel is 1/5, and the probabilty to get Q on the other wheel is 1/3
so, P(Q, 4) = 1/3 × 1/5 = 1/15
Answer:
-1.3
Step-by-step explanation:
3v+1+7v=-12 equation
10v+1=-12 combine like terms
10v=-13 subtract 1 from both sides
v=-1.3 divide by 10
