Answer:
1/50
Step-by-step explanation:
Given that:
- Three men: 3
- Seven women = 7
- Total number of people: 7+3 =10
We need to find the probability that no man will be interviewed until at least two women have been interviewed. So there are two possible probabilities are:
1. One man and two women => P(1 man and 2 women) = 3/10*2/9 = 1/15
2. Three women => P(3 women) = 3/10
Hence, the probability in this situation is: 1/15*3/10 = 1/50
Answer:
Length of rectangular lawn =72 meters
Breadth of rectangular lawn =18 meters
Perimeter of rectangle =2(Length+Breadth)
So, Perimeter of rectangle =2(72+18)=2(90)=180 meters
If three shrubs can be planted in a meter of hedge.
Then, Number of shrubs planted in whole perimeter will be=3×180=540
Step-by-step explanation:
You want to find 
; that is, given that you randomly choose from the pool of women, the probability that she does not exercise.
By definition of conditional probability,
496 of the total 1026 people are woman, and 341 of the 1026 people are women and do not exercise, so
A simpler way of doing this is to look at what's called the marginal distribution of women in the table. Basically this comes down to ignoring all but the data pertaining to the women. There's a total of 496 women, and 341 of them do not exercise. So the probability that a given woman does not exercise is 341/496.
Answer:
100-29=71
71-23=48
48/2=24
Therefore, 24-4=20
answer =20
