Answer:
The probability is 1/8 or 0.125.
Step-by-step explanation:
Given is that three fair coins are flipped.
And we have to find the probability of getting a head on the first flip,a tail on the second flip, and another head on the third flip.
Firstly, here each flip is independent of the outcome of the other flips.
So, the probability of head is 1/2 and the probability of tail is 1/2.
Therefore, the answer will be : (1/2) (1/2) (1/2)=8
Answer:
1:4
Step-by-step explanation:
There are only two colours available, red and green. We know that there are 11 red marbles and 55 marbles altogether, so the number of green marbles must be 55 - 11, or 44. That means that the ratio of red to green marbles is 11:44, or 1:4.
