2 yellow marbles, 7 red marbles, 1 green marble.....total of 10 marbles
probability of first picking a yellow marble : 2/10 reduces to 1/5
replacing the marble
probability of picking another yellow marble : 2/10 reduces to 1/5
probability of both is : 1/5 * 1/5 = 1/25 <==
Answer:
Gareth has a deck of cards with 12 challenge cards and 8 prize cards.
=> The probability he selects a prize card: P = 8/(12 + 8) = 8/20 = 0.4
Gareth is going to randomly select a card from the deck 148 times, replacing the card and shuffling the deck after each selection .
=>The randomness is kept same for all selecting times
Then the best prediction for the number of times Gareth will select a prize card:
=> N = 0.4 x 148 = 59.2 = 59 times
Hope this helps!

16(3b−0.25)
=(16)(3b+−0.25)
=(16)(3b)+(16)(−0.25)
=48b−4
Answer: $2.80
Step-by-step explanation: .80×3 is 2.40 plus half of .80 is 2.80
The answer here is B. -16
10 + -16 equals -6 and a negative divided by a negative is a positive so -6 divided by -3 is -2.
Hope this helps!
