Suppose we flip a coin 13 times and it is weighted so the probability of getting a heads (a success) is .65.    What is the probability of getting at most 6 heads?  P (x < 6)  (Round to four decimal plac

Suppose you are conducting a test of significance to try to determine whether your cat, Hope, will go to the correct object (out of two) when it is pointed to. You test Hope 100 times and finds she goes to the correct object in 70 out of those 100 trials. In this scenario, what is the variable? Whether or not Hope goes to the correct object The 100 trials The proportion of the 100 trials that Hope goes to the correct object The long term proportion (probability) that Hope will go to the correct object

A bag contains (x + 1) yellow balls, x black balls and (x – 1) white balls. Probability of getting a yellow ball is (2/15) more than that of getting a white ball. Find the value of x.

i don't understand how to solve this.
