Answer:
9/100
Step-by-step explanation:
There are 10 marbles in the bag
There are 3 pink marbles.
P (1st marble pink) = pink marbles/ total marbles
= 3/10
We put the marble back.
There are 10 marbles in the bag
There are 3 pink marbles.
P (2nd marble pink) = pink marbles/ total marbles
= 3/10
Multiply the probabilities together
P (pink, then pink) = 3/10 * 3/10 = 9/100
47.098 rounded to the nearest tenth is 47.1
B. 13
12^2 + 5^2 = c^2
169 = c^2
13 = c

Answer:
0.64
Step-by-step explanation:
P(J / R) = P (J and R) / P(R)
0.8 = P (J and R) / 0.6
P (J and R) = 0.6 * 0.8 = 0.48 [Probability John practicing and it is raining]
P(J / NR) = P (J and NR) / P(NR)
0.4 = P (J and NR) / (1 - 0.6) = P (J and NR) / 0.4
P (J and NR) = 0.4 * 0.4 = 0.16 [Probability John practicing and it is not raining]
Hence;
Probability of John practicing regardless of weather condition is
P(John Practicing) = 0.48 + 0.16 = 0.64
HOPE THIS HELPED!!!
