Answer: 44% of the students are boys.
Step-by-step explanation:
We know the total number of students is 25 and the total number of boys is 11 so you divide 11 by 25 then multiply by 100 to get the percentage. Ex. 11/25=0.44 0.44 x 100= 44. Answer 44%

Answer:
0.6836 = 68.36% probability that the player will win at least once.
Step-by-step explanation:
For each game, there are only two possible outcomes. Either the player wins, or the player loses. The probability of winning a game is independent of any other game, which means that the binomial probability distribution is used 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.
25% chance of winning
This means that
Plays the game four times
This means that
What is the probability that the player will win at least once?
This is:
In which
0.6836 = 68.36% probability that the player will win at least once.
