You could buy $7 for each tin of popcorn and get 8, $8 for 7 tins of popcorn, or $4 for 14 tins of popcorn
Answer:
The probability of getting two heads and a four is 1/24
Step-by-step explanation:
The probability of getting a head upon a single toss of a coin, assuming the coin is fair is 1/2.
The probability of getting two heads upon tossing two coins together will simply be the product of the individual probabilities;
P (HH) = 1/2 * 1/2 = 1/4
On the other hand, the probability of getting a four upon rolling a six sided number cube is;
1/6
This is because the number 4 occurs only once in a total possible of 6 numbers.
Therefore, the probability of getting two heads and a four;
P (HH4) = 1/2 * 1/2 * 1/6 = 1/24 since the three events are independent.
Answer:
9
Step-by-step explanation:
The answer is in the picture below this:
The probability is 0.336.
To solve this, we need Binomial Probability equation for Repeated Trials.
P = nCr (p)^r (q)^(n-r)
where P = probability (unknown)
n = number of trials (8)
r = number of successes (1)
p = probability of success (.20)
q = probability of failure (0.80)
P = 8C1 (.20)^1 (.80)^7
= 0.336
