1 |
Problem |
A card is drawn at random from deck of cards. Find the probability that the card drawn is neither a queen nor jack.? |
|
2 |
Step |
The event E is neither a queen nor jack = p(E) |
|
3 |
Clue |
Deck of cards = \$13 \times 4\$ |
52 |
4 |
Step |
Total number of outcomes |
52 |
5 |
Step |
since there are 4 queens and 4 jacks so |
52-8 = 44 |
6 |
Step |
The number of favorable outcomes is neither a queen nor a jack |
44 |
7 |
Formula: |
P(E) =\$"Number of favorable outcomes" / "Total number of possible outcomes"\$ |
|
8 |
Step |
The probability of this event occuring is |
p(E) = \$\frac(44)(52)\$ |
9 |
Step |
After simplification |
P(E) = \$\frac(11)(13)\$ |
