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)

Answer:
3x - 11
Step-by-step explanation:
( x - 4 ) + ( 2x − 7 )
*it's better to take away the parenthesis
x - 4 + 2x - 7
Combine like terms
( x with 2x, and -4 with -7)
3x - 11
And you cannot simplify it anymore
Hope this helped!
