Hello :
cos²(θ) +sin²(<span>θ) = 1
(1/4)² +sin²(</span><span>θ) = 1
</span>sin²(θ) = 1 -1/16
sin²(θ) =15/16
sin(θ) = - √(15/16)=- √15/4 because : <span>sin θ < 0.
</span>tan (θ) =sin (θ)/ cos( θ) =(- √15/4)/(1/4) = - √15

Step-by-step explanation:
Given that a manufacturer makes three types of screws
Type A B C Total
Pack 1000 500 800
P for flaw 0.001 0.03 0.005
Pack*p 1 15 4 20
a) Expected total number of defective screws = 20
b) For one pack each no of defective screws =20
Hence for 5 expected number number of packs form each should be 1/3
