90 POINS QUES

Answer 1

Step-by-step explanation: When a coin is tossed it can be either head or either tail.

So the probability of getting 1 head out of 3 heads and 3 tails in 3 coins in 5 times will be_

                     No . of favourable items

PROBALITY=--------------------------------------

                          Total no . of  items

   therefore,   3  ×  5 (times)          15      1

                     --------------------    =    ---- =  ----

                       6   ×  5 (times)        30      2

And the probability of getting 1 tail  out of 3 heads and 3 tails in 3 coins will also be_

                    3  × 5 (times)           15              1

                  --------------------      =   ----     =    ------
