for part a (on the second picture) there are 10C1=8 ways to make the first letter. Thus the probability of getting that letter is 3/10. To get the last letter, there are also 10 permutations, thus the probability is 2/10. Can you solve the rest?

do you have any progress for the first question (coffee)?

#

ok

#

how did you get those numbers?

#

wouldn’t you want to account for repetition?

#

hm

#

well, there’s likely an easier way to solve this

What repetition?

lofty bay What repetition?

there’s three Ts in statistics

Oh, I see.

#

i suppose, if you consistently count them as different, it should cancel out when applying the probability

#

i think so, yes

#

not for the second picture

#

reef widget i *think* so, yes

divide by 2 to account for the two Ss

#

it is just finding the probability
