Answer:
x + 7x = (25.6)(12.5)
8x = 320
x = 40, so (1/4)(40) = 10
There would be 10.8 ounces in each jar.
Answer:
Step-by-step explanation:
Correct option is C)
There are 15 boys and 10 girls in a class
We have to select 3 students such that there should be 1 girl and 2 boys
The number of ways we can select 3 students is
25C3=2300
The number of ways we can select 3 students such that there is 1 girl and 2 boys is 15×7×10=1050
The probability is 1050/2300 =21/46
Therefore the correct option is C
finding the number of combinations for the desired scenario and the total possible combinations, we find that the probability is 21/46.
In order to solve this problem, we need to apply the principles of combinatorics and probability. The total number of students in the class is 25 (10 boys and 15 girls). Firstly, let's calculate the combinations for the scenario of selecting 1 boy out of 10. This can be done by 10C1 resulting in 10 possibilities. Secondly, let's calculate the combinations of selecting 2 girls out of 15, which is 15C2 and gives us 105 possibilities.
Multiply those together to find the total scenario we're interested in, which is 1,050. The total possible combinations of selecting 3 students out of 25 irrelevant of gender would be 25C3, resulting in 2,300 possible combinations.
Therefore, the probability that the selected students are 1 boy and 2 girls is 1,050/2,300. Simplifying this fraction gives us 21/46.
