Two coins are tossed 600 times and we get two heads : 138 times, one head : 192 times ; no head : 270times. When two coins are tossed at random, what is the probability of getting : 1 head?

I am getting 6/75 or 0.08

is it correct?

Total outcomes = 4 x 600 = 2400

1 head= 192

so, 192/2400

From the experiment , you get 1 head 192 out of 600 times so the probability is 192 / 600 = 0.32

But aren't total outcomes going to be 4 x 600?

No. 1 event is tossing the two coins once (at the same time). The possible outcomes for 1 event are 2 heads, 1 head or no heads. The event occurs 600 times. Out of those 600 times, you get 1 head, 192. so probability is 192 / 600.
