Answer:
Check Explanation
Step-by-step explanation:
The days of the week include
Sunday
Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
a) So, the possible letters to be taught include
A, D, E, F, H, I, M, N, O, R, S, T, U, W, Y
There are indeed 15 possible letters.
These are the letters from which all the days of the week are formed from.
b) There are more than 4 letters that can't be taught using this method.
All the letters that cannot be taught using this method because no day of the week contains them include
B, C, G, J, K, L, P, Q, V, X, Z
c) In Tuesday, there are 7 distinct letters.
So, the sample space consist of 7 letters.
n(sample space) = 7
n(Y) = 1
Probability of picking a Y = (1/7)
The reasoning is simple, picking a Y on a Tuesday is one out of 7 possible outcomes, so, the probability of picking a Y on a Tuesday to teach the kid about = (1/7) = 0.143
Hope this Helps!!!
