Step-by-step explanation:

Given that in the game Scrabble, there are a total of 100 tiles. Of the 100 tiles, 42 tiles have the vowels A, E, I, O, and U printed on them, 56 tiles have the consonants printed on them, and 2 tiles  are left blank.

a. If tiles are selected at random, the probability that the first tile drawn from the pile of 100 tiles is a vowel =

b. If tiles drawn are not replaced,  the probability that the first two tiles selected are both vowels =

c. Event A is drawing a vowel, event B is drawing a consonant, and event C is drawing a blank tile. A1 means a vowel is drawn on the first selection, B2 means a consonant is  drawn on the second selection, and C2 means a blank tile is drawn on the second selection. Tiles are selected at random and without replacement.

i. Find P(A1 and B2). =

ii. Find P(A1 and c2). =

iii. Find P(A1 and A2).=

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
