arrive late. Valerie used the random-number table to find the experimental probability that of 5
flights, at least 2 will arrive late. The digit 0 represents flights arriving early. The digits 1,2,3,
4, 5, and 6 represent flights arriving on time. The digits 7, 8, and 9 represent flights arriving
late. Find the experimental probability that of 5 flights at least 2 will arrive late.
A: 3/10
B:2/5
C: 9/20
D: 11/20
Answer:
D. 11/20
Step-by-step explanation:
7, 8, and 9 represent late flights. We want to count how many of the 20 trials have at least two of these digits. Counting, we find that 11 of the 20 have at least two of these digits.
D. 11/20
Isaiah need 10 weight to balance the scale.
What is Division method?
Division method is used to distributing a group of things into equal parts.
Given that;
Isaiah put a 100 gram weight on a pan balance.
Now,
Number of 10 gram weight to balance the scale = 100 ÷ 10
= 10
Thus, Isaiah need 10 weight to balance the scale.
