Hello,

In order to be simple: let's code hexadecimal numbers on 4 digits.

Example: 500-200=300 (in décimal)

$500_{10}=01F4_{16}\\\\
200_{10}=00C8_{16}\\\\
For\ subtract\ 00C8\ we\ calculate\ 15th\ complement\\\\
C_{15}(00C8)=FF37\\\\

16th\ complement= FF37+0001=FF38\\\\

Then\ we\ add\\\\

01F4+FF38=(1)012C\ on\4\ digits:\ 012C\\

012C_{16}=300_{16}

A bunch of mixed colored roses has 5 red roses, 3 pink roses, 2 white roses, and 2 yellow roses. What is the probability of draw

svp [43]

Answer:

the probability of drawing a pink rose from the bunch of roses is 25%

Step-by-step explanation:

assuming that each rose es equally likely to be chosen then the probability of picking one pink rose is

probability = number of pink roses / total number of roses = 3 / (5+3+2+2) = 3/12 = 0.25 (25%)

then the probability is 25%
