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

Option 3 - 0.5

Step-by-step explanation:

Given : Dion flips a coin 20 times and records if it comes up heads. If getting heads is a success.

To find : What is the probability of a success on each roll?

Solution :

We have to find the probability of a success on each roll

In 1 roll either heads comes either tail

Favorable outcome (head was drawn) = 1

Coin has only two faces,

Total number of outcome = 2

Probability of a success on each roll is

Therefore, Option 3 is correct.

answer: idk

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
