$\huge\mathbb\fcolorbox{purple}{lavenderblush}{✰αηsωεя࿐}$

a. false

Sin ø can't be equal to 4/3 because value of sinø lies between -1 to +1 it can't have Value greater than 1. so it is not possible. no such angle exist

b. true

In an experiment, the probability of an event is the likelihood of that event occuring. Probability is a value between (and including) zero and one. If P(E) represents the probability of an event E, then: P(E) = 0 if and only if E is an impossible event

c. true

The value of tan theta increases from 0° to 90°

d.true

In the question it is known that abbreviation of cosecantA=coescA ,cosineA=cosA. So we can see that clearly the given statement cosA is the abbreviation used for the cosecant of angle A is false. Hence option B is the correct answer.
