Answer:
1/8 ;
12 / 51
Step-by-step explanation:
To select any 5 numbers out of 40
Number of selection required / total numbers
Probability of winning = 5 /40 = 1/8
Total number of socks = 18
White, W = 8
Black, B = 6
Blue, C = 4
probability, without looking in the drawer, that you will first select and remove a black pair, then select either a blue or a white pair?
P(B) * [(P(C) + P(W)]
Probability = required outcome / Total possible outcomes
P(B) = 6 / 18 = 1/3
Without replacement :
P(W or C) = 8/17 + 4/17 = 12/17
Hence,
1/3 * 12/17
= 12 / 51
The number of pages in the book is actually irrelevant.
Franco reads 30 pages in 1 night. To find how many pages he reads in 7 nights, just multiply by 7.
30*7=210
Franco reads 210 pages in 7 nights.
Solving with Equivalent Ratios:
The ratio of pages he reads per night is 30:1. We need to figure out the ratio <em>x</em>:7, where the variable <em>x</em> is the number of pages he reads in 7 nights.
30:1=<em>x</em>:7
To find x we need to see the similarity between both ratios. This is found by dividing two of the equal sides, here it would be 7 and 1.
7/1=7
This means that the second ratio is 7 times the first ration. To find <em>x</em>, just multiply 30 by 7.
30*7=210
Franco reads 210 pages every 7 nights.
