Answer:

the probability of getting 5 from standard deck is 4/52 and probability to get tails from a flipped coin is 1/2

Step-by-step explanation:

as there are 4 parts in card i.e spade diamonds hearts and clubs which has 13 cards each from each 13 cards there are one 5 card so there are 4 cards with 5 number in standard deck

there is only one tails in a coin

Answer:

The order doesn’t matter, as the two events are probabilistically independent of one another. There are 13 spades in a standard 52 card deck, so the probability of drawing  the number 5 is 13/52 or 1/4. The probability of heads is 1/2. The probability of both occurring is the product of the two probabilities, or 1/4*1/2 = 1/8 or 12.5%.

F(x)= √x-5. find f-2
rodikova [14]

For this case we have:

Be a function of the form y = f (x)

Where:

f (x) = \sqrt {x-5}

If we want to find f (-2), we substitute x = -2, then:

f (-2) = \sqrt {-2-5}\\f (-2) = \sqrt {-7}

Since we have a negative root, the result will be given by complex numbers. By definition:

\sqrt {-1} = i

So:

f (-2) = \sqrt {7} i

Answer:

f (-2) = \sqrt {7} i
