01:00 - 01:59 | head means minimum we should get one head and maximum we can get two heads two heads case will be included in at least one head because minimum we should have one head and maximum we can get to head so we can include this case we conclude this case we can include this because we are getting one had here we can include this case to because we are getting one head here so favourable outcomes for at least one heads will be equal to we have Total 3 February outcomes of probability will be equal number of favourable |

02:00 - 02:59 | outcomes upon we have total outcomes so we have number of favourable outcomes as we have three favourable outcomes a pond we have total focuses so we have total for outcomes of the probability will be 3 by 4 thank you |
