Methods for estimating the impact probability of asteroids 99942 Apophis and 2011 AG5 were implemented. The probability of a collision was assessed using two methods: The Monte Carlo method(statistical experiments), and as a ratio between the interval of values of orbital elements, leading to a collision, and the confidence intervals of orbital elements. It was established that the main contribution to the estimation of the impact probability makes a variation in the semimajor axis. The expected date and the estimate of the probability of collisions of asteroids 99942 Apophis and 2011 AG5 with the Earth were computed.
Mots-clés : 99942 Apophis, orbital elements
