Answer:
1/9
Step-by-step explanation:
135 in Sport centre: Total
59:swimming pool
31:track
19 both swimming and gym
16 gym and track
4 all three facilities
4 people use all three facilities, then
16 - 4 = 12 people use the gym and the track and do not use the pool;
9 - 4 = 5 people use the pool and the track and do not use the gym;
19 - 4 = 15 people use the gym and the pool and do not use the track.
At least two facilities use 4 + 12 + 5 + 15 = 36 people, 4 of them use all three facilities. Thus, the probability that a randomly selected person which uses at least two facilities, uses all the facilities is
4/36=1/9
Hope this helps!!!
Answer:
C) The centers will roughly be equal, and the variability of simulation A will be less than the variability of simulation B.
Step-by-step explanation:
The center for Simulation A and Simulation B will be roughly equal.
Overall Sample size of Simulation A = 1500 * 100 = 150000
Overall Sample size of Simulation B = 2000 * 50 = 100000
Since the sample size for Simulation A is greater, the variability of Simulation will be less.
Therefore, The answer is C) The centers will roughly be equal, and the variability of simulation A will be less than the variability of simulation B.
Answer:
The circumference is 31.42 and the area is 78.54
Step-by-step explanation:
For circumference you use the formula
C=2 r
R= radius and = 3.14
For area use the formula
A= r^2

Answer:
1/6
Step-by-step explanation:
two events need to happen: tutti frutti needs to be shown by first spinner and second spinner needs to show dish
probability of tutti frutti = 1/3
probability of dish = 1/2
probability of both events = 1/3 * 1 /2 = 1/6
Total number of students = 10
As we have to find
P(A/B) = Probability( A when B has happend)
P(A/B)= P(A intersection B)/P(B)
According to given figure only yolanda and Rob are in both club
Therefore,P(A intersection B) 
Number of student in karate club =6
P(B)
P(A/B) 
Converting division into multiplication by reciprocating the term after division
P(A/B) 
On solving we get ,
P(A/B) 
P(A/B)
P(A/B)
