Isolate the variable by itself on one side of the equation.
0.6y=10.3 divide both sides of the equation by 0.6
y=10.3/0.6 (we can multiply both numerator and denominator by 10 to get rid of decimals...)
y=103/6 or as a mixed number
y=17 1/6
So probility is (disired outcomes) divided by (total possible outcomes) so
1st one is white roses
8 white roses so 8 is disired
total=5+3+8=16
8/16=1/2
then without replacing them
red=5
total possible=16-1 since 1 picked
5/15=1/3
then multiply the probatilities
1/2 times 1/3=1/6
it is a 1 in 6 probability
Here is my work. Hope it helps.
