(70 -100)/15 = -2 . . . . the z-score of a score of 70

p(z < -2) ≈ 2.3%

A score of 70 would place you in approximately the 2nd percentile.

Yuri [45]

Answer:

A

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

Here b = 13 and h = 4 , thus

A = \frac{1}{2} × 13 × 4 = \frac{1}{2} × 52 = 26 units² → A

a) both are cups is 0.05

b) At least one cup is 0.19

c) One is a cup and the other is a sword is   0.06

<h3 /><h3>What is probability?</h3>

Probability can be defined as the ratio of favorable outcomes to the total number of events.

a) for both are cups

P= 12*11/48*47
p = 0.05

b) for  At least one cup
p = 12*36/48*47
p = 0.19

c) for One is a cup and the other is a sword
p = 12*12/48*47
p = 0.06

Thus, the required probability is 0.05, 0.19, 0.06
