Q and r are not mutually exclusive events. if p(q) = 0.12, p(r) = 0.25, and p(q and r) = 0.03, find p(q or r).
2 answers:
So we are given the probabilities of q and r:
p (q) = 0.12
p (r) = 0.25
p (q and r) = 0.03
Actually to find for p (q or r), this simply means to add
all the values of p (q). p (r) and p (q and r). If we are to draw a bubble
diagram, the p (q and r) is the bubble intersection p (q) and p (r). We know
that the word “OR” takes up all in the bubble diagram. Therefore:
p (q or r) = p (q) + p (r) + p (q and r)
Substituting the given values into the equation:
p (q or r) = 0.12 + 0.25 + 0.03

Answer:
0.34
Step-by-step explanation:
The probability of A or B occurring if they are not mutually exclusive is given by
P(A)+P(B)-P(A and B)
In this case, we have
P(q)+P(r)-P(q and r)
= 0.12+0.25-0.03 = 0.34

Answer:
c = 5
Step-by-step explanation:
- 6 + 2c = 3c -(6+5)
-6 + 2c = 3c -11
-6 + 11 = 3c- 2c
5 = c

Answer:
125
Step-by-step explanation:
The total number of marbles is 6+10 = 16
P (black) = black / total
= 10/16 = 5/8
With 200 draws, take the probability of P(black) times 200 since the marble is returned each time
200 * (5/8) = 125
We would expect to get 125 black marbles
Answer:
I'm taking an educated guess here and saying that its option two.
I haven't done these problems in almost two years.
12 x 16 = 192 square inches
