(b)What is the probability of choosing the letter A at random from the word ALPHABET?
lakkis [162]

Answer:

3b: 1/26

4i: 1/4

4ii: 1/13

4iii 1/13

4iv: 1/13

4v: 3/13

Step-by-step explanation:

3b. there are 26 letters in the alphabet, and there is only 1 S, thus the answer is 1/26

4i: There are 13 cards in each suite, so there is a 13/52 = 1/4 chance.

4ii: There are four aces (Spades, Hearts, Diamonds, and Clubs) so thus the answer is 4/52 = 1/13

4iii: there are four 7's (Spades, Hearts, Diamonds, and Clubs) so thus the answer is 4/52 = 1/13

4iv: there is a king in each of the suites, therefore the answer is 4/52 = 1/13

4v: there are a total of 12 court cards (4 kings, 4 queens, and 4 jacks) thus the answer is 12/52 = 3/13

Find three consecutive even numbers whose sum is 1674.
Norma-Jean [14]

Answer:

556, 558, and 560

Step-by-step explanation:

1674/3 = 558 (An even number, yay)

So 558 + 558 + 558 = 1674

Subtract two from the first one and add two to the last (still equal)

556 + 558 + 560

adding them equals 1674 so the answer is

556, 558, and 560
