Probability of an event =
(number of ways the event can happen) / (total number of possible outcomes) .
Well, the total number of possible outcomes is easy. It's
(6 possibilities for the first cube) x (6 possibilities for the 2nd cube)
= 36 total possible ways for two cubes to roll.
Now, how many of those possibilities show either 4 or 7 ?
Well, here's how a 4 can come up:
1 . . . 3
2 . . . 2
3 . . . 1
and here's how a 7 can come up:
1 . . . 6
2 . . . 5
3 . . . 4
4 . . . 3
5 . . . 2
6 . . . 1 .
So there are 9 ways all together for Lenny to be successful.
The probability is (9/36) .
That's 1/4 , or 25% .
No, her answer is not reasonable because one yard is equal to 3 feet.
Answer:
$10
Step-by-step explanation:
cost of one month of game play = x
1(35) + 3x + 2(35) + 5x = 185
35 + 70 + 8x = 185
105 + 8x = 185
-105 -105
8x = 80
/8. /8
x =10
.8 it represents .80 cents. rather than .08 which would represent 8 pennies
Jessica runs fastest because her time/second is about 10 seconds while brookes is around 12.
