i cant see the photo its messy or is it just me
Step-by-step explanation:
Answer:
a) 9
Step-by-step explanation:
f(2) basically equals to y when x=2 and the y coordinate at x=2 is 9
Step-by-step explanation:
the probability is always the number of desired cases over the number of all possible cases.
in our situation we have 15 cards.
that is the total possible cases when a random card is chosen.
how many desired cases do we have ?
a number NOT a multiple of 5.
how many are there ?
it is easier to say how many numbers there are being a multiple of 5 : 5, 10, 15
so, 3 numbers out of the 15 are multiple of 5.
that means
15 - 3 = 12 numbers of the 15 are NOT multiples of 5.
so, the probability to draw a card that is not a multiple of 5 is
12/15 = 4/5 = 0.8
the information about event B and even numbers is irrelevant for the question.
137/100,
EXPLANATION:
Replace the decimal with a fraction sign.
