Answer:

Step-by-step explanation:
Given that the bag contains black and red marbles.
Number of black marbles in the bag = 2
Number of red marbles in the bag = 3
Total number of marbles in the bag = Number of black marbles + Number of red marbles = 2 + 3 = 5
Let us have a look at the formula for probability of an event E, which can be observed as:


Now, the marble chosen at first is replaced.
Therefore, the count remains the same.

Now, the <em>required probability</em> can be found as:

Answer:
(12, 3)
Step-by-step explanation:
write the equation:
if x = number of 2 point shots
and y = number of 3 point shots
2x + 3y = 33
write another equation with the total baskets
x + y = 15
plug them both into desmos and find the solution
(12, 3)
she made 12 2-point shots and 3 3-point shots
9514 1404 393
Answer:
A) 5x+12 = -12x-12
D) 5x+12 = -5x-12
Step-by-step explanation:
If you subtract the right side expression from both sides, you will get an equation with something equal to zero. If the 'something' has a variable in it, there is exactly one solution.
A: (5x+12) -(-12x-12) = 17x+24 = 0 . . . one solution
B: (5x+12) -(5x-5) = 17 = 0 . . . . no solutions
C: (5x+12)-(5x+12) = 0 = 0 . . . . infinite solutions
D: (5x+12) -(-5x-12) = 10x +24 = 0 . . . one solution
Answer:
The probability of choosing a yellow marble is 2/13
Step-by-step explanation:
There are 2 yellow and 11 blue marbles in the bag or a total of 13 marble
P(yellow) = number of yellow marbles / total marble
= 2/13
The probability of choosing a yellow marble is 2/13
