What is 5/16 written as a percent?

Rom4ik [11]

First, you divide the fraction, and then you multiply it by 100.
So you get:
$\frac{5}{16} * 100$
$0.3125 * 100$
$31.25$

So, 5/16 is 31.25%

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)
