Let a be the event that there are at least two fives among the four rolls. let b be the event that there is at most one five among the four rolls. find the probabilities p(a) and p(b) by finding the ratio of the number of favorable outcomes to the total (i. e., p(a) = #a #ω and p(b) = #b #ω ).

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
