<p>majors do not influence ur chance of admission, unless it is impacted in which in that case you will not be able to switch to that impacted major...</p>
<p>I would advise you to choose the major or at least the department that you would like to study. The typical strategy of majoring in non-competitive field but switching to a competitive one e.g. engineering has one fault. Some UC's might not let you make a change stating that specific college or major is full. Being stuck in your Junior year of college would definitely not be fun. Therefore, I would advise you to apply to the major or at least to that department. However, thats just my opinion, I may be wrong...</p>
