Answer:
The correct option is C 20.1%.
Step-by-step explanation:
The probability distribution chart representing the opinions of employed adult women about government funding for day care is as follows:
Rating (<em>X</em>) Probability (<em>p</em>)
1 0.110
2 0.206
3 0.464
4 0.201
5 0.119
The ratings are defined as follows:
1: too little
2: helpful but not enough
3: make a difference but insufficient
4: sufficient
5: generous
The probability of women who think that the support is sufficient is, 0.201.
The percentage is: 0.201 × 100 = 20.1%
Thus, the percentage of women who think that the support is sufficient is 20.1%.
The correct option is C.
Answer:
A) The best way to picture this problem is with a probability tree, with two steps.
The first branch, the person can choose red or blue, being 2 out of five (2/5) the chances of picking a red marble and 3 out of 5 of picking a blue one.
The probabilities of the second pick depends on the first pick, because it only can choose of what it is left in the urn.
If the first pick was red marble, the probabilities of picking a red marble are 1 out of 4 (what is left of red marble out of the total marble left int the urn) and 3 out of 4 for the blue marble.
If the first pick was the blue marble, there is 2/4 of chances of picking red and 2/4 of picking blue.
B) So a person can have a red marble and a blue marble in two ways:
1) Picking the red first and the blue last
2) Picking the blue first and the red last
C) P(R&B) = 3/5 = 60%
Step-by-step explanation:
C) P(R&B) = P(RB) + P(BR) = (2/5)*(3/4) + (3/5)*(2/4) = 3/10 + 3/10 = 3/5
Answer:
type of angles is complementary
equation is (3x-5)+x=90
x=23.75
As shown in the figures given :
For Figure 1 : perimeter = 8 units [As can be seen in the figure]
For figure 2(with 2 octagons) : perimeter = 8 × 2 - 1 = 15 units [since 1 side is common ]
For figure 2(with 3 octagons) : perimeter = 8 × 3 - 2 = 22 units [since 2 sides is common ]
If one more octagon is added
then perimeter = 8 × 4 - 3 = 29 units [since 3 sides will be common ]
