Answer:
1/ 3
Step-by-step explanation:
If each of the cards is turned over, the probability of picking up a card of one type P(E) becomes equal to:
=> P(E) = number of cards of the required type/ total number of cards
● Total number of spades( ♤ ) = 3
{the queen, one ace and the nine are all spades}
● Total number of cards = 6
Probability of drawing a spade= 3/ 6
= 1/ 2
● Total number of "7" = 1
● Total number of cards = 6
Probability of drawing a 7
= 1/ 6
Now, what's asked is the difference in the probabilities of drawing a spade and a seven.
= 1/ 2 - 1/ 6
= 3/ 6 - 1/ 6
= 2/ 6
= 1/ 3
Hence, 1/ 3 of a greater chance of drawing a spade over a 7.
Answer:
-1 23/64
Step-by-step explanation:
First change the 2 mixed numbers to single fractions:-
3 5/8 = (3*8+ 5) / 8 = 29/8
-2 2/3 = - (2*3 + 2/ 3 = -8/3
so we have 29/8 / -8/3
Invert the -8/3 then multiply:-
= 29/8 * -3/8
= -87/64
= -1 23/64 (answer)
Answer:
Sorry I cant answer this,
Step-by-step explanation:
More explanation and fix grammar.
We answer the question by substituting 5 to all the x's of the given function,
f(x) = 2x² + 2
Substituting,
f(5) = 2(5²) + 2 = 52
Thus, the f(5) is equal to 52. The answer is letter B.
