Acoin is tossed.

what is the probability of the coin landing heads up?

a. 1/2

b. 1/4

c. 1/6

d. 1/3

1/2

Step-by-step explanation: In this problem, we're tossing a coin and we want to find the probability of tossing a heads.

Now, let's find the probability of tossing a heads.

Remember that a coin has two sides which are heads and tails. When you flip a coin, each side is as likely to come up as the other. This means that the probability of flipping heads is the fraction 1/2.

Since the probability of flipping a heads is 1/2, we can also say that the probability of flipping a heads is 50%.

Therefore, the probability of flipping a heads on a fair coin is 1/2.

3/20

Step-by-step explanation:

Red = 3

Blue = 3

Green = 4

Total = 3+3+4 = 10

Pr (red) = 3/10

Pr blue) = 3/10

Pr (green) = 4/10

Where Pr = probability

You either have a head or a tail when tossing a coin

Probability of having head = 1/2

Probability of having tail = 1/2

The probability of the coin landing heads up and blue marble = Probability of head ×Pr (blue)

= 1/2 × 3/10

the probability of the coin landing heads up and blue marble = 3/20

The probability of the coin landing on heads is 1/1 which is 1 and the probability of the blue marble is 7/3.

Step-by-step explanation:

the probability of the coin, E=1 from[HH,HT]

                                            S=1 so P=1/1=1

the probability of all of the marbles=3+3+4/3=10/3

so to get the probability of the blue marble=10/3-3/3=7/3
