1/2 - 5/12= 6/12 - 5/12 = 1/12
The original price was 100% and the sale was -25%
100% - 25% = 75%
This means 75% = £33
75% = 3/4
If we divide the sale amount by 3 and them multiply by 4, we will get the original amount.
£33 / 3 = £11
£11 x 4 = £44
Answer:
0.9451
Step-by-step explanation:
Remaining question? <em>"How is the result affected by the additional information that the survey subjects volunteered torespond?"</em>
Probability that at least 1 user is more careful about personal information when using a public Wi-Fi hot spot is:
P(X≥1) = 1 − P(X<1)
= 1 − P(X=0)
= 1 - [(3,0) (0.62)^0 (1-0.62)^3-0
= 1 - 0.054872
= 0.945128
= 0.9451
Thus, the probability that among three randomly selected Internet users; at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.9451
