For 1 toss of a certain coin, the probability that the outcome llbe heads is 0.6. If this coin is tossed 5 times, which of the following is teh probability that the outcome will be heads atleast 4 times ?
1) (0.6)^5
2) 2(0.6)^4
3) 3(0.6)^4 (0.4)
4) 4(0.6)^4 + (0.6)^5
5) 5(0.6)^4 (0.4) + (0.6)^5
OA [spoiler]= 5[/spoiler], but why is there a "5" multiplied to (0.6)^4 . Is it a typo ?
1) (0.6)^5
2) 2(0.6)^4
3) 3(0.6)^4 (0.4)
4) 4(0.6)^4 + (0.6)^5
5) 5(0.6)^4 (0.4) + (0.6)^5
