Answer:
125
Step-by-step explanation:
that would be , by proportion. 5 * 800 / 32
= 125 students
0.123 is the ratio of 123 to 1,000 .
It's perfectly rational.
Hint:
ANY number that you can write down completely
on paper with digits is rational.
We know that
red marbies=3------> r=3
green marbies=4----> g=4
blue marbies=3-----> b=3
total marbles in the bag=r+g+b-----> 3+4+3-----> 10
a) <span>probability of randomly selecting a green (g) marble
P(green)=g/total marbles------> 4/10-----> 2/5
b) </span>probability of randomly selecting a red (r) marble
the marble is replaced so we have the same total marbles
P(red)=r/total marbles------> 3/10
c) <span>Total probability of selecting this path is:
P(green)*P(red)-----> (2/5)*(3/10)-----> 6/50----> 3/25----> 0.12 (12%)
the answer is
0.12 (12%)</span>
it's B because the input is put together in only one output.
