Answer 1

Step-by-step explanation:

The probability that the card is black will be 26/52=13/26=1/2

Answer 2

Answer:

$let \\ the \: sample \: space \: be \: s. \\in \: the \: pack \: of \: cards \: total \: numbers \: of \: card \: is \: 52 \\ n(s) = 52 \\ let \: a \: be \: the \: event \: of \: getting \: black \: cards \: \\ n(a) = 26 \\ we \: know \: that \\ p(a) = \frac{n(a)}{n(s)} \\ p(a) = \frac{26}{52} \\ p(a) = \frac{1}{2} \\ the \: probability \: of \: getting \: black \: card \: is \: \frac{1}{2} .$
