Probability = 0.502
Step-by-step explanation:
We are given the following data :
Hours Count Percent
1 18 3.44
2 55 10.50
3 81 15.46
4 109 20.80
5 88 16.79
6 66 12.60
7 39 7.44
8 17 3.24
9 17 3.24
10 19 3.63
15 15 2.86
We need to calculate the probability
P(Length of stay of exactly 1 is less than or equal to 4)
P() = P(Y = 1) + P(Y = 2) + P(Y = 3) + P(Y = 4)
We convert the percent into probabilities by dividing them with 100. This gave us the required probabilities.
Answer:
c.
Step-by-step explanation:
Given,
Number of bacterias who alive for at least 30 days = 5,
Bacterias who alive for 2 days = 10,
Died bacterias = 10,
Total bacterias = 5 + 10 + 10 = 25,
Ways of choosing a bacteria = =
= 25,
While, ways of choosing of a bacteria who will live after 1 week = =
= 5,
Hence, the probability it will still be alive after one week = =
