what is the probability that the first letter is a
what is the probability that the first letter is z
what is the probability that the first letter is a vowel
what is the probability that the first letter is h

(a) 0.28, (b) 0.14, (c) 0.57 and (d) 0.

Step-by-step explanation:

Probability =

where,

FO represents favorable outcomes and TO represents total outcomes

(a) In this part, FO = 2 and TO = 7

So, the probability =

= 0.28

(b)  In this part, FO = 1 and TO = 7

So, the probability =

= 0.14

(c)  In this part, FO = 4 and TO = 7

So, the probability =

= 0.57

(d)  In this part, FO = 0 and TO = 7

So, the probability =

= 0

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

the first option is the answer.
