calculate the probability of drawing a: blue card, then drawing another blue card, with no replacement. answer as a fraction in lowest terms. enter the numerator.
Answer
Answer:
$\frac{1}{15}$
Explanation:
Step1: Count total and blue cards
There are 10 cards in total, 3 blue cards.
Step2: Probability of first - draw
The probability of drawing a blue card first is $\frac{3}{10}$.
Step3: Probability of second - draw
After drawing one blue card without replacement, there are 9 cards left and 2 blue cards left. So the probability of drawing a blue card second is $\frac{2}{9}$.
Step4: Calculate combined probability
The probability of both events is $\frac{3}{10}\times\frac{2}{9}=\frac{6}{90}=\frac{1}{15}$.
