Answer:
A. 18%
Step-by-step explanation:
For independent events:
P(A and B) = P(A) × P(B)
P = 0.30 × 0.60
P = 0.18
There is an 18% probability that it will rain on both days and the game will be canceled.
Answer:
option 4
Step-by-step explanation:
using the sine/ cosine ratios in the right triangle and the exact values
cos30° =
, sin30° =
, then
cos30° =
=
=
( cross- multiply )
2x = 20
×
= 20 × 3 = 60 ( divide both sides by 2 )
x = 30
and
sin30° =
=
=
( cross- multiply )
2y = 20
( divide both sides by 2 )
y = 10
