doing the math like this works but for me it was easier to think about like this
probability ssx
52/52 * 12/51 * 39/50= .183
probability sxs
52/52 * 39/51 * 12/50= .183
probablity sxx
52/52 * 39/51 *12/50= .183
.183+.183+.183= 55%
Exactly the same thing but just wanted to write it out like that cause like i said was easier for me to think about this way
