151° OP

161° OP

51° OP

610 OP​

Answer 1

Answer:

Step-by-step explanation:

It is because the bag does not contain any red ball so there is no chance to draw a red ball. Hence probability of drawing a red ball is zero.

Answer 2

Answer:

61° OP 4th option

Explanation:

Given,

Concentration of alcohol = 92%

Find,

The over proof percentage of the given alcohol sample.

Solution,

Proof spirit contains 57.1% V/V alcohol.

That is 57.1% V/V = 100

Then 92% V/V = ?

=$\frac{100}{57.1} *92$

=161

Over proof = $161-100$

=61°
