Answer:
C) 3.0
Step-by-step explanation:
Let the length of the other side be x.
Using Pythagoras theorem for right-angled triangle,
4.2^2=2.9^2+x^2
or,x^2=4.2^2-2.9^2
or,x^2=9.23
or,x=√9.23=3.0 units
there are 4 Aces and 4 8's for a total of 8 cards
52 cards in a deck
so probability of picking an Ace or 8 = 8/52
