Answer:
The probability that they each will catch 3 fish is 0.000063956
Step-by-step explanation:
The hyper geometric distribution is used to solve this as it has a population, a sample , number of successes for both the population and sample.
Here
Population size= N =200
Sample size= n =9= (3*3)
Number of successes in population = k = 3 hours
Number of successes in sample = x= 3
Applying the hyper geometric distribution
P (x=3) = kCx *(N-k) C (n-x)/ N Cn
= 3 C 3 * 197 C 6/ 200 C 9
=0.000063956
The probability that they each will catch 3 fish is 0.000063956
Answer:
8 pen : 26
15 pen : 60
Step-by-step explanation:
5 pen = 20
Times both sides by 2
10 pen = 40
add 5 pen = 20
15 pen = 60
Divide 10 by 5
2 pen = 4
1 pen = 2
Add them together
3 pen = 6
Add 5 pens and 20
8 pen = 26
Answer:
56 cm Squared
Step-by-step explanation:
area of rectangle =10×5=50
area of smaller rectangle =3×2=6
area of the shape is 56
3u + 4u + 2u = 9u
9u = 90
1u = 90/9 = 10
since black is 2u ( from the ratio given)
2u = 10 x 2 = 20
Answer : 20cm of the pole is painted black.
