From an urn containing 3 white and 2 black balls, two balls are drawn one after the other without replacement. What is the proba

Marina86 [1]

Answer:

There is a 3/5 chance of the first ball being white, and a 3/10 chance the second one is black.

Step-by-step explanation:

There are 5 balls, of which 3 are white, so you have a 3/5 chance of the first one being white. Then you have 2 white and 2 black balls. There is a 2/4 chance of picking a black ball. Multiply 3/5 and 2/4 to get 6/20, or 3/10 for choosing a white ball then a black ball.

If Tanø =a/b Find the value of sinø+cosø/sinø-cosø

inysia [295]

Answer:

$\frac{b+a}{b-a}$

Step-by-step explanation:

Tan θ = $\frac{perpendicular}{base}$ = $\frac{b}{a}$

So, Perpendicular = b, base = a

Finding hypotenuse by Pythagorean Theorem:

$c^2 = a^2+b^2$

=> So, hypotenuse = c

Sin θ = $\frac{perpendicular}{hypotenuse}= \frac{b}{c}$

Cos θ = $\frac{base}{hypotenuse}= \frac{a}{c}$

So, Now finding $\frac{sin\theta+cos\theta}{sin\theta-cos\theta}$

=> $\frac{b}{c} + \frac{a}{c}$ ÷ $\frac{b}{c} - \frac{a}{c}$

=> $\frac{b+a}{c}$ ÷ $\frac{b-a}{c}$

=> $\frac{b+a}{c} * \frac{c}{b-a}$

=> $\frac{b+a}{b-a}$
