Question

Jenny has a deck of 52 alphabet cards (26 uppercase and 26 lower case). Jenny selects one card. Suppose Jenny selected a vowel on her first draw, what is the probability she selects a vowel on her second draw?

Answer 1

Step 1: We have to determine the probability of the event " a vowel " in the second draw, when a vowel was selected in the first draw.

Step 2: The probability will be computed with the formular:

`\text{probability = }\frac{\text{ number of favourable outcome}}{total\text{ number of outcome}}`

Step 3: As determine in the second draw the sample space is 51 letters , 26 consonants and 25 vowels

Step 4: Out of 51 outcome, the favourable outcome are those which contain a vowels : 9 outcomes

Step 5: The probability of the event

`\text{Probability(a vowel at second draw) = }(9)/(51)=(3)/(17)`

Therefore the probability she selects a vowel on her second draw = 3/17
