Answer:
Step-by-step explanation:
We want to solve for x in the equation in
Let us group like terms to obtain:
We now combine the terms to get:
Divide both sides by 4
Answer:
A. 1/9
Step-by-step explanation:
In order to find probability, you need to add up the total number of cards Dana has.
14 + 10 + 8 + 4 = 36
Then set up a fraction representing probability.
4 hockey cards
---------------------
36 total cards
Simplify

---
9
This means that Dana has a 1 out of 9 chance of getting a hockey card.

Using the binomial distribution, it is found that there is a 0.03125 = 3.125% probability that all the nickels will land with heads facing up.
For each coin, there are only two possible outcomes, either it lands on heads, or it lands on tails. The landing of a coin is independent of other coins, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- 5 nickels, hence .
- They are equally as likely to land on heads or tails, hence
The probability that all the nickels will land with heads facing up is P(X = 5), hence:
0.03125 = 3.125% probability that all the nickels will land with heads facing up.
