7:can make 3 bracelets with 4 beads left over
8: 3 groups with 8 left over
Answer:
11/30
Step-by-step explanation:
You need to convert everything to a common denominator, so you would change everything into x/30 so 7/10 is equal to 21/30 and 1/3 is equal to 10/30 so you would just subtract 21-10 and get 11/30
The probability that all three people surveyed is an independent probability and the calculated probability is 0.1225
The probability a surveyed driver is worried = 35%
- Number of people surveyed = 3
Since the probability of being worried is independent ;
- Probability = P(A) × P(B) × P(C)
The probability that all 3 surveyed are worried :
- P(worried) × P(worried) × P(worried)
- (0.35 × 0.35 × 0.35) = 0.1225
Therefore, the probability that all three people surveyed are worried is : 0.1225

Answer:
B. 0.132
Step-by-step explanation:
For each time the dice is thrown, there are only two possible outcomes. Either it lands on a five, or it does not. The probability of a throw landing on a five is independent of other throws. 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.
Timothy creates a game in which the player rolls 4 dice.
This means that
The dice can land in 6 numbers, one of which is 5.
This means that
What is the probability in this game of having exactly two dice or more land on a five?
In which
So the correct answer is:
B. 0.132
Step-by-step explanation:
14(0)-3(0)(9)-3(0)(9)+6(0)-9
=0-0-0+(-9)
