One card is drawn from a well shuffled deck of \[\mathbf{52}\] cards. Find the probability of getting: \[\left( \mathbf{v} \right)\] a diamond or a spade

Solution:

\[\left( v \right)\] Number of favorable outcomes for a diamond or a spade \[=\text{ }13\text{ }+\text{ }13\text{ }=\text{ }26\]

So, number of favorable outcomes \[=\text{ }26\]

Hence, P(getting a diamond or a spade) \[=\text{ }26/52\text{ }=\text{ }1/2\]
