A card is drawn at random from a well-sheffled deck of cards numbered 1 to 20 then find a probability of getting a number divisible by 3.? |
|
2 |
Step |
The event E is getting a number divisible by 3 = P(E) |
|
3 |
Clue |

52 |
4 |
Step |
Total number of outcomes |
20 |
5 |
Step |
The number of favorable outcomes is number which is divisible by 3 |
|
6 |
Formula: |
P(E) =\$"Number of favorable outcomes" / "Total number of possible outcomes"\$ |
|
7 |
Step |
The probability of this event occuring is |
P(E) = \$\frac(6)(20)\$ |
8 |
Step |
After simplification |
P(E) = \$\frac(3)(10)\$ |
