Answer:
1/2 or 0.5
Step-by-step explanation:
Within 1 to 6,
Even numbers are 2, 4, 6
While odd numbers are 1, 3, 5
Assuming cards are mixed up properly and the probabilities of drawing a card with any number from 1 to 6 is constant,
Probability of drawing even number cards = number of units of even number cards ÷ total number of units of cards from 1 to 6 aka total number of cards
= 3 / 6
= 1 / 2
N is greater than or equal to -10
Because the function f(x) =-2+√x+7 has √x, x should be more or equal 0.
Domain is x≥0, or [0,+∞).
The smallest value of x=0, so the smallest value of f(x) is f(0) =-2+√0+7=5,
so range is f(x)≥5, or [5, +∞).
