Answer:
Correct option: C -> 2%
Step-by-step explanation:
To find this probability we just need to divide the area of the bull's-eye circle by the total area of the outer circle.
The area of a circle is given by the equation:
The outer radius is 14 cm, so:
The inner radius is 2 cm, so:
So the probability is:
Correct option: C
1/3÷5
=1/3×1/5
=1/15
each child receive 1/15 of cake
3x³ - 2x² + 1 = 0
By definition, a quadratic equation cannot have an exponent higher than 2.
there are 4 of the 10-nf and 8 of the 100-nf capacitors which is a total of 12 items.
the probability of drawing a 10-nf is: 4 out of 12 =
the probability of drawing a 100-nf is: 8 out of 12 =
(a) "at least two" means: 2 or 3 or 4
Probability of 2 (10's) and 2 (100's): x x x =
Probability of 3 (10's) and 1 (100's): x x x =
Probability of 4 (10's) and 0 (100's): x x x =
2 or 3 or 4: + + =
(b) without replacement
2 or 3 or 4: + + = = =
