Fifty balls are numbered 1 to 50 and red dot is painted on those balls that are a multiple of 8. the balls are mixed into a bag
vaieri [72.5K]
Total number of balls = 50
Balls numbered as multiple of 10 = 5
Balls with red dot on them = 6
Balls numbered as multiple of 10 and having red dot on them = 1 (i.e. Ball with number 40 on it)

Probability of Ball being numbered as multiple of 10 = P(T) = 5/50 = 1/10

Probability of Ball being marked by the dot = P(D) = 6/50 = 3/25

Probability of Ball being numbered as multiple of 10 and having a red dot on it = P (T ∩ D) = 1/50

The "or" ,"union" of two events can be expressed as:

P(T ∪ D) = P(T) + P(D) - P (T ∩ D)

Using the values, we get:

P(T ∪ D) = \frac{1}{10} + \frac{3}{25}- \frac{1}{50}=1/5

Thus, the probability that the ball is numbered with a multiple of 10 or has a red dot is 1/5 or 0.2

Solve sint = cos2t, for –4π ≤ t ≤ –2π
e-lub [12.9K]

Answer:

-(23/6)π

-(19/6)π

-3π

Step-by-step explanation:

cos2t=cos^2t-sin^2t => cos^2t=1-sin^2t =>cos2t=1-2sin^2t

sint=1-2sin^2t, if x=sint, thenn we have 2x^2+x-1=0

Here x=0.5, x=-1, as x=sint => sint = -1 solutions for -4π to -2π is t=-3π,

sint = 0.5 solutions for -4π to -2π is t= -(23/6)*π, and t = -(19/6)*π
