The answer is 180 minutes. because you multiply 30 times 0.20 and you get 6. Then you multiply 6 times 30 and get 180 minutes. And 180 minutes in hours is 3 hours.

laiz [17]

Answer: $\dfrac{76}{89}$

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 = $\dfrac{76}{89}$
