Ira Lisetskai [31]3 years ago
5 0

Answer:

Option B is correct.

Step-by-step explanation:

B- Spinning “back 2 spaces” on a spinner is a simple event. The probability that it will get 2 spaces back from where it started first is a single event.

A involves probability of landing 2 spaces back along with the probability of drawing a blue or red marble from a box. This is compound event.

C also involves 2 probabilities.The probability of getting an odd number on a die plus the probability of getting tails on the toss of a coin.  

D involves 5 probabilities with one probability for each toss.  

Therefore, option B is correct.

sammy [17]

They met 480 meters from the house.

<h3><u>Calculus</u></h3>

Given that Noah and his grandfather were returning home from a walk, and when they were 800 m away from the house, the grandfather said that he was thirsty, so Noah immediately ran home, got a bottle of water, and ran back to meet his grandfather who never stopped walking at a steady pace, to determine how many meters from the house did they meet if noah ran four times as fast as his grandfather walked, the following calculation must be made:

  • 200 x 4 = 800 - 200 = 600
  • 300 x 4 = 1200 - 800 - (800 - 300) = 100
  • 325 x 4 = 1300 - 800 - (800 - 325) = -25
  • 320 x 4 = 1280 - 800 - (800 - 320) = 480 - 480 = 0

Therefore, they met 480 meters from the house.

Given that events A and B are independent with P(A)=0.3P(A)=0.3 and P(A\cap B)=0.27P(A∩B)=0.27, determine the value of P(B)P(B),
Stolb23 [73]

Answer:

0.9

Step-by-step explanation:

Since A and B are independent  hence;

P(A∩B) = P(A)P(B)

Given the following

P(A∩B) = 0.27

P(A) = 0.3

Required

P(B)

Substitute into the formula;

P(B) = P(A∩B)/P(A)

P(B) = 0.27/0.3

P(B) = 0.9

Hence the value of P(B) is 0.9
