I got
3/5x = -1/5
x = -1/3
Because two negative equal out to a positive not a negative. Hope this helped sorry if it’s wrong.
Answer:
The P(x=45) is more that the P(x=20). Therefore x=45 successes is more likely to get.
Step-by-step explanation:
Given information: n=100 and p=1/3.
According to the binomial distribution, the probability of getting r success in n trials is

where, n is total trials, p is probability of success and q is probability of failure.
Total trials, n = 100
Probability of success, p = 
Probability of failure, q = 
The probability of 20 successes is


The probability of 45 successes is


The P(x=45) is more that the P(x=20). Therefore x=45 successes is more likely to get.
Answer:
B
Step-by-step explanation:
Symmetric means one side looks the same as another side such as a square. It isn't symmetric because the other side doesn't have the same side as the other so it isn't bell shaped and isn't symmetric
Answer:
It's D. 5
