You add 12 and 6 up and then multiply that result by 1/2, so your answer would be 9.
Answer:
9/32
Step-by-step explanation:
given that an ant is moving on a numbered, horizontal line every second
Probability for moving left = 1/4
and prob for moving right =3/4
As this totals 1, there is no chance that ant will remain in the same posiiton after 1 second.
Either it has to move left or right.
Initial position is 0.
After 3 seconds it is in position 1.
The chances are I second move left, next second, move right and come to 0 and third second move to 1.
Or
I second move right, then left to 0, and third again to right to 1.
There are no other alternatives
Probability for this =

Answer:
60
Step-by-step explanation:
To find the percentage, multiply by the number of total cookies by the decimal conversion of the percentage. Sugar cookies are 30% since 60% is oatmeal and 10% is chocolate chip.
30% is 0.30. The number of sugar cookies is 200*0.30 = 60.
