Answer:
θ = 2π/3 or 5π/3
Step-by-step explanation:
2 cosθ + 1= 0
when + 1 goes to R H S Side than it becomes negative by transposition method
2 cos = -1
now by dividing by 2 both sides we get
cosθ = -
since cosθ is negative
Cosθ = - cos 60°
it means either cosθ lies in 2nd or third quadrant
θ = π - π/3
or
θ = 2π- π/3
so θ = 2π/3 or 5π/3
Answer:

Step-by-step explanation:
Please find the complete question in the attached file.
In point a:
P(a substantive term only)
P(major health insurance only)
P(both)
P(renewal) =P(insurance and renewal term only)+P (substantial and renewable health insurance only)+P (both and renew)
In point b:
In reality, the probability of having both life and major medical insurance provided the policyholder would renew next year
