3 0

Answer:

Ф = 19.80 °

Step-by-step explanation:

by using pythagoras theorem

h² = p² + b²

13² = 5² + b ²

b = √194

b = 13.93

now

tanФ  = p/b

Ф = tan¬1( 5 / 13.93)

Ф = 19.80 °

A fair spinner has 11 equal sections: 3 red, 4 blue and 4 green. It is spun twice. What is the probability of getting the same c
Aliun [14]

Answer:

The probability of getting the same colour twice is approximately 34%.

Step-by-step explanation:

The probability of getting each color is:

  • P(x=red) = 3/11
  • P(x=blue) = 4/11
  • P(x=green) = 4/11

Then, we can calculate the probability of getting the color red twice as:

P(x_1=R;x_2=R)=P(x=R)^2=(3/11)^2=9/121

We have to repeat this for the color blue and green:

P(x_1=B;x_2=B)=P(x=B)^2=(4/11)^2=16/121\\\\P(x_1=G;x_2=G)=P(x=G)^2=(4/11)^2=16/121

Then, the probability of getting the same color twice in two spins can be calculated as:

P=P(x_1=R;x_2=R)+P(x_1=B;x_2=B)+P(x_1=G;x_2=G)=\\\\P=9/121+16/121+16/121\\\\P=41/121\approx0.34
