Answer;
[tex]\text{ Pr(a four and a heart) = }\frac{1}{52}[/tex]Explanations:
Probability is the likelihood or chance that an event will occur. The formula for calculating probability is expressed as;
[tex]\text{Probability = }\frac{n(E)}{n(S)}[/tex]n(E) is the total number of event
n(S) is the total number of sample space
Since there are 52 cards in a deck of cards, hence the total number of sample space will be 52
n(S) = 52
In a deck of cards. there are four 4's, 1 per suite and there is only ONE 4 which is a heart.
If a four AND a heart was selected, then the total number of events n(E) is 1
The probability that the card is a four AND a heart will be:
[tex]\text{ Pr(a four and a heart) = }\frac{1}{52}[/tex]
