How to Solve (3/4+1/2)

1 answer:

4 0

First you want to make the fractions similar.

to do this you need to make the denominators (the botom part of each fraction) the same.
so you can multiply 1/2 by two DO NOT MULIPLY THE FRACTION AS A WHOLE that would not be good lol
you will multiply
1*2=2
2-2=4
now your fraction will be 2/4

now lets place that back into the equation
3/4+2/4=?
now to solve this the denominators will stay the same.
we only add the top number
3+2= 5

so our answer will be 5/4 or 1 1/4

Get a common denominator of 100 for the first term

13/10 * (10/10) +2/100=?/100

130/100 + 2/100 = ?/100

132/100 = ? /100

Somebody help me solve;

P(at least 5 rolls until 1) = P(4 rolls are not 1) = 5/6 x 5/6 x 5/6 x 5/6 = 0.4823 (4sf)

Fewer than 7 rolls to get second 1 after first takes 3 rolls means second occurs on 4th, 5th or 6th roll
The probability of each of these is 1/6, 5/6 x 1/6 and 5/6 x 5/6 x 1/6 respectively.
P(second 1 on 4th, 5th or 6th roll) = 1/6 + 5/36 + 25/216 = 91/216 = 0.4213 (4sf)

I don’t know how to solve this problem

The draws are independent, so

$P(\text{red then blue})=P(\text{red})\cdot P(\text{blue})$
