Answer:

1/5

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability that he pulls out a red marble = number of red marbles / total number of marbles

= 4/20 = 1/5

locksmith larry charges $90 for a house cal plus $20 per hour. Locksmith Barry charges $50 for a house call plus $30 per house.
nadya68 [22]

Answer:

<u>4 hours</u>

Step-by-step explanation:

Equations :

Larry : <u>y = 20x + 90</u>

Barry : <u>y = 30x + 50</u>

Equate both to find the number of hours at which they both charge the same :

  • 20x + 90 = 30x + 50
  • 30x - 20x = 90 - 50
  • 10x = 40
  • x = <u>4 hours</u>

7.56/2.4 = 3.15, 

p= 3.15
