Step-by-step explanation:

The pool of rats from which the researcher is drawing participants is composed of the following:

23 male albino rats

21 male spotted rats

35 female albino rats

11 female spotted rats

Total rats = 23+21+35+11 =90

P(male\ albino)=\dfrac{23}{90}

After drawing first rat , total rats remained = 89

P(\text{either a female albino rat or a male spotted rat})=\dfrac{35+21}{89}=\dfrac{76}{89}

The probability of choosing a male albino rat and then either a female albino rat or a male spotted rat = \dfrac{76}{89}
