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>

x=12.22
Answer:
PETER 18
POL 21
MARY 26
Step-by-step explanation:
I dont know if I did in the right way...
1st: Take any number for peter's or pol's age
I took 18 for peter, RANDOMLY
2nd: Subtract the age from the total to get pol's age
39-18=21 Hence, pols age is 21
3rd: Subtract peter's age from the total to get marys age
47-18=26 Hence, Marys age is 26
4th: Add the age of pol and mary
aaand, you get 47
Done!
Hope it helps!!!
Answer:
A) 4
Step-by-step explanation:
Area of a triangle formula:
A = 0.5bh
Given:
b = 4
h = 2
Work:
A = 0.5bh
A = 0.5(4)(2)
A = 2(2)
A = 4
