Binomial Probability
Jay was reaching into her purse and accidentally
spilled her coin purse. 10 pennies fell on the floor. Jay
noticed that only 2 of the pennies landed on heads.
- What is the theoretical probability of this happening?

4.39% theoretical probability of this happening

Step-by-step explanation:

For each coin, there are only two possible outcomes. Either it lands on heads, or it lands on tails. The probability of a coin landing on heads is independent of other coins. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

Theoretically, a fair coin

Equally as likely to land on heads or tails, so

10 coins:

This means that

What is the theoretical probability of this happening?

This is P(X = 2).

4.39% theoretical probability of this happening

step-by-step explanation: noo

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
