Dion flips a coin 20 times and records if it comes up heads. if getting heads is a success, what is the probability of a success on each roll? .
0.2.
0.3.
0.5.
1.00

0.5.

Step-by-step explanation:

A probability is the division of the number of desired outcomes by the number of total outcomes.

In this problem:

A coin can be either heads or tails, so there are two possible outcomes.

The desired outcomes is heads, so there is one desired outcomes.

So the probability of a success on each roll is 1/2 = 0.5

x = 12

y = 15

step-by-step explanation:

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
