Answer : 5/22
A deck of cards contains 6 black cards and 6 red cards. The first card drawn is not replaced before drawing the second card.
Total number of outcome of cards = 12
Probability( any event)= favorable outcomes divide by total number of outcomes
Probability of selecting black card =
The drawn card is not replaced . so 11 cards left . In that 11 cards, 5 black cards because one black card is already chosen
Probability of selecting another black card =
Probability of selecting a black card followed by another black card =
=
=
Answer:
<h2>b = 16.7</h2>Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side b
Using Pythagoras theorem we have
a² = b² + c²
where
a is the hypotenuse
Substituting the values into the above formula we have
<h3>We have the final answer as
<h3>b = 16.7 to one decimal place</h3>Hope this helps you
