Answer:
about 1.56637 radians ≈ 89.746°
Step-by-step explanation:
The reference angle in radians can be found by the formula ...
ref angle = min(mod(θ, π), π -mod(θ, π))
Equivalently, it is ...
ref angle = min(ceiling(θ/π) -θ/π, θ/π -floor(θ/π))×π
<h3>Application</h3>
When we divide 11 radians by π, the result is about 3.501409. The fractional part of this quotient is more than 1/2, so the reference angle will be ...
ref angle = (1 -0.501409)π radians ≈ 1.56637 radians ≈ 89.746°

<em>Additional comment</em>
For calculations such as this, you need to use the most accurate value of pi available. The approximations 22/7 or 3.14 are not sufficiently accurate to give good results.
The answer is -7, because a whole number is any number between zero and POSITIVE infinity. Negative seven does not fall under this.
To find the probability, you write a fraction with the number of expected outcomes to total possible number of outcomes.
a) Red - 25/100
b) Purple -55/100
c). There is a 25% or 1 in 4 chance to select a red bulb and a 55% or 5 in 11 chance of selecting a purple bulb.
